DiceBear — Free Avatar Generator API (No Key)

TL;DR

DiceBear is a free avatar generator API that creates unique, deterministic avatars based on a seed string. With over 20 avatar styles — including pixel art, bottts, identicon, avataaars, lorelei, adventurer, fun-emoji, and more — you can generate consistent profile pictures for any user by passing their username or ID as the seed. The API returns SVG images that scale infinitely, with PNG output also available. Customization options include background color, primary color, and style-specific options like accessories, clothing, and facial features. No API key or rate limits.

  const url = `https://api.dicebear.com/9.x/pixel-art/svg?seed=${seed}`;
  const img = document.createElement('img');
  img.src = url;
  img.alt = `${user.name}'s avatar`;
  img.className = 'avatar';
  document.getElementById('user-list').appendChild(img);
});

Frequently Asked Questions

What avatar styles are available?: Over 20 styles: pixel-art, bottts, identicon, avataaars, lorelei, adventurer, adventurer-neutral, big-ears, big-ears-neutral, big-smile, croodles, croodles-neutral, fun-emoji, icons, initials, micah, miniavs, notionists, notionists-neutral, open-peeps, personas, ring, shapes, thumbs, and more. Each style produces a distinct visual aesthetic.
How does the seed mechanism work?: The seed string determines the avatar deterministically — the same seed always produces the exact same avatar. Use a username, user ID, email, or any unique string. For extra uniqueness, combine multiple fields: ?seed=username-123.
Can I customize colors and other options?: Yes! Most styles support common options: backgroundColor (hex without #), primaryColor, secondaryColor, and textColor. Style-specific options vary — for example, avataaars supports accessories, top, hairColor, facialHair, clothes, etc. Check the style's docs for details.
What output formats are supported?: SVG (scalable vector) is the primary format, returned by default. For PNG raster output, use /png instead of /svg in the URL path. PNG supports a size parameter for dimensions. SVG is recommended for most use cases due to quality and file size.
Is there a rate limit or need for an API key?: No API key required and no documented rate limit. DiceBear is free for both personal and commercial use. For very high-traffic applications, consider self-hosting the open-source generator.
Can I use DiceBear in commercial products?: Yes! All avatar styles are free for any use, including commercial applications, SaaS products, mobile apps, and websites. Some style artwork may have specific licenses — check the DiceBear website for style-specific attribution requirements.
